Session Entry Restore or SandBox Feature

Anyway to be able to restore a specific session entry as I know you can compare session modifications to see what has changed however you can not do a restore only write down the changes and go back to you session and manually add them in.
(1) Have the ability to restore from a specific entry in version history or (2) have RDM be able to revert or remember previous settings in a session or (3) have the ability to send a session to a sandbox for testing of setting changes.
I know you can create a duplicate of a session and apply changes to it for testing and delete the duplicate but I was not expecting that the username & domain in an RDP session would be blank once I tested a new credential entry I created.
